SALOMON BROTHERS VARIABLE SERIES FUNDS INC
Our Message to You

DEAR SHAREHOLDER:
We are pleased to provide you with the semi-annual report for the Salomon
Brothers Variable Investors Fund ("Fund") for the period ended June 30, 2000.
This letter discusses general economic and market conditions as well as major
Fund developments during the reporting period. A detailed summary of performance
and current Fund holdings can be found in the appropriate sections that follow.
We hope you find this report to be useful and informative.

INVESTMENT STRATEGY1
The Fund continues to focus on stocks with attractive valuations and favorable
earnings growth prospects. And while no guarantees can be made, we are confident
that our value strategy should continue to reward shareholders over time.

PERFORMANCE UPDATE
The Fund's shares returned 9.16% for the six-month period ended June 30, 2000.
In comparison, the Standard & Poor's 500 Index ("S&P 500") returned a negative
0.43% and the Lipper Inc.'s peer group of large cap value funds returned a
negative 1.65% for the same period.2

MARKET REVIEW
In the first half of this year, the stock markets experienced increased
volatility. Technology stocks continued to drive the market through early March.
The momentum behind technology stocks came at the expense of most other sectors
of the market, including consumer staples, financials and pharmaceuticals.
During this period, the Fund added to these out-of-favor sectors. In mid-March,
investors took profits in technology stocks and rotated into undervalued
sectors. Specifically, defensive sectors such as consumer staples, healthcare
and energy all performed well as investors continued to worry about the Federal
Reserve Board's ("Fed") reaction to inflationary pressures. The Fund benefited
from the increase in market breadth.

For the six-month period, the significant decline in a number of large-
capitalization stocks held back the performance of the S&P 500. Microsoft, which
represented 4.9% of the S&P 500 at year-end, declined 31.5%, which alone
penalized the S&P 500 by 1.5 percentage points. Other notable decliners included
Lucent, America Online, AT&T, Home Depot, Procter & Gamble and Qualcomm, all of
which fell more than 20%. Including Microsoft, these eight stocks accounted for
about 13% of the S&P 500 at year-end.

     intended to be a forecast of future events. There is no assurance that
     certain securities will remain in or out of the Fund.
2    The Standard & Poor's 500 Index ("S&P 500") is a market
     capitalization-weighted measure of 500 widely held common stocks. Lipper,
     Inc. is a nationally recognized organization that reports on total return
     performance and calculates rankings based on total returns. Total returns
     are calculated based on changes in NAV including the reinvestment of
     dividends and capital gains. Past performance is not a guarantee of future
     results. An investor cannot invest directly in an index.

HIGHLIGHTS
The Fund performed quite well in the first six months, significantly outpacing
both its large-cap value peer group and the S&P 500. During the first quarter,
we continued to trim most of our technology holdings due to valuation concerns.
We redeployed those proceeds into other sectors of the market that offered much
more attractive valuations. In particular, we added consumer staples, financials
and pharmaceuticals, all of which rebounded as investors rotated out of
technology. Since the correction in technology in mid-March, we have been adding
to selected tech stocks on weakness in the sector. We plan to continue
increasing our weighting in technology as we see opportunities to do so.

Our overweight position in consumer staples contributed to the Fund's
outperformance during the period. In particular, Nabisco Group Holdings, Pepsi
Bottling Group, Safeway and Kimberly Clark all were strong performers. Nabisco
Group Holdings was the Fund's top contributor during the period as a result of
the planned sale of the company.

In other sectors, leading contributors included News Corporation, Intel, Eli
Lilly and Coastal Corp., among others. Laggards included International Paper,
Compuware, Tyson Foods, Federated Department Stores and UnumProvident. The Fund
no longer owns Compuware and UnumProvident.

OUTLOOK
Recent economic data suggest that the economy may be slowing; however,
inflationary concerns are likely to keep the Fed on guard. We expect recent
stock market volatility to persist. Uncertainty over economic growth and
prospective Federal Reserve actions will continue to result in market swings.
Fortunately, market breadth remains favorable.

Currently, the Fund has overweight positions versus the S&P 500 in consumer
staples, communications, energy and financials. As a result of the merger
between Bell Atlantic and GTE, the Fund's top position is now Verizon
Communications, the newly combined entity. The Fund is underweight in
technology, capital goods and consumer cyclicals. As mentioned above, we
continue to look for opportunities to add to technology stocks. Overall, we
believe that the Fund is well positioned for the current market environment in
which individual stock selection plays a more important role than sector
momentum.

We appreciate your investment with the Salomon Brothers Variable Investors Fund
and we look forward to serving your financial needs in the new century.

Cordially,

+    Assumes the reinvestment of all dividends and capital gains distributions
     at net asset value. Total returns do not reflect expenses associated with
     the separate account such as administrative fees, account charges and
     surrender charges which, if reflected, would reduce the total returns for
     all periods shown. Total returns may also reflect a voluntary expense cap
     imposed by Salomon Brothers Asset Management Inc. to limit total Fund
     operating expenses. Absent this expense cap, total returns for the Fund
     would be lower. Expense caps may be revised or terminated.
++   Total return is not annualized, as it may not be representative of the
     total return for the year.

1. Organization and Significant Accounting Policies

Salomon Brothers Variable Investors Fund ("Fund") is a separate diversified
investment portfolio of the Salomon Brothers Variable Series Funds Inc
("Series") whose primary investment objective is to seek long-term growth of
capital and secondarily current income. The Series, a Maryland corporation, is
registered under the Investment Company Act of 1940, as amended ("1940 Act"),
as an open-end management investment company and consists of this Fund and
seven other investment portfolios: Salomon Brothers Variable Capital Fund,
Salomon Brothers Variable Total Return Fund, Salomon Brothers Variable High
Yield Bond Fund, Salomon Brothers Variable Strategic Bond Fund, Salomon
Brothers Variable Small Cap Growth Fund, Salomon Brothers Variable U.S.
Government Income Fund and Salomon Brothers Variable Asia Growth Fund. The U.S.
Government Income Fund and Asia Growth Fund have not yet commenced operations.
The financial statements and financial highlights for the other investment
portfolios are presented in separate shareholder reports. The Fund and each
other investment portfolio of the Series is offered exclusively for use with
certain variable annuity and variable life insurance contracts offered through
the separate accounts of various life insurance companies and qualified pension
and retirement plans.

The significant accounting policies consistently followed by the Fund are: (a)
security transactions are accounted for on trade date; (b) securities traded on
national securities markets are valued at the closing prices on such markets;
securities traded in the over-the-counter market and securities for which no
sales price was reported are valued at the mean of the current bid and asked
prices; debt securities are valued using either prices or estimates of market
values provided by market makers or independent pricing services; securities
and assets for which market quotations are not readily available are valued at
fair value as determined in good faith by or under the direction of the Board
of Directors of the Fund; (c) securities maturing within 60 days are valued at
cost plus accreted discount, or minus amortized premium, which approximates
market value; (d) dividend income is recorded on the ex-dividend date; foreign
dividend income is recorded on the ex-dividend date or as soon as practical
after the Fund determines the existence of a dividend declaration after
exercising reasonable due diligence; (e) interest income, adjusted for
accretion of original issue or market discount, is recorded on the accrual
basis; (f) gains or losses on the sale of securities are calculated by using
the specific identification method; (g) dividends and distributions to
shareholders are recorded on the ex-dividend date; (h) the accounting records
are maintained in U.S. dollars. All assets and liabilities denominated in
foreign currencies are translated into U.S. dollars based on the rate of
exchange of such currencies against U.S. dollars on the date of valuation.
Purchases and sales of securities, and income and expenses are translated at
the rate of exchange quoted on the respective date that such transactions are
recorded. Differences between income and expense amounts recorded and collected
or paid are recorded as currency gains or losses; (i) the character of income
and gains to be distributed are determined in accordance with income tax
regulations which may differ from generally accepted accounting principles. At
December 31, 1999, reclassifications were made to the capital accounts of the
Fund to reflect permanent book/tax differences and income and gains available
for distributions under income tax regulations. Accordingly, a portion of
overdistributed net investment income amounting to $12,084 was reclassified to
paid-in capital. Net investment income, net realized gains and net assets were
not affected by this change; (j) the Fund intends to comply with the applicable
provisions of the Internal Revenue Code of 1986, as amended, pertaining to
regulated investment companies and to make distributions of taxable income
sufficient to relieve the Fund from substantially all Federal income and excise
taxes; and (k) estimates and assumptions are required to be made regarding
assets, liabilities and changes in net assets resulting from operations when
financial statements are prepared. Changes in the economic environment,
financial markets and any other parameters used in determining these estimates
could cause actual results to differ.

Organization costs amounting to $31,250 were incurred with the organization of
the Fund. These costs are being amortized ratably over a five year period from
commencement of operations.

2. Management Agreement and Transactions with Affiliated Persons

Salomon Brothers Asset Management Inc ("SBAM"), a wholly owned subsidiary of
Salomon Brothers Holding Co. Inc., which, in turn, is wholly owned by Salomon
Smith Barney Holdings, Inc. ("SSBH"), acts as investment manager to the Fund.
Under the investment management agreement, the Fund pays an investment
management fee calculated at the annual rate of 0.70% of its average daily net
assets. This fee is calculated daily and paid monthly.

SBAM also acts as administrator to the Fund. As compensation for its services
the Fund pays SBAM a fee calculated at an annual rate of 0.05% of its average
daily net assets. This fee is calculated daily and paid monthly. SBAM has
delegated its responsibilities as administrator to SSB Citi Fund Management LLC
("SSBC"), formerly known as SSBC Fund Management Inc., an affiliate of SBAM,
pursuant to a Sub-Administration Agreement between SBAM and SSBC.

CFBDS, Inc. acts as the Fund's distributor. For the six months ended June 30,
2000, Salomon Smith Barney Inc., another subsidiary of SSBH, and its affiliates
received brokerage commissions of $276.

3. Investments

During the six months ended June 30, 2000, the aggregate cost of purchases and
proceeds from sales of investments (including maturities, but excluding short-
term securities) were as follows:

<TABLE>
<S>                                                                  <C>
Purchases........................................................... $42,080,479

</TABLE>

At June 30, 2000, the aggregate gross unrealized appreciation and depreciation
of investments for Federal income tax purposes were substantially as follows:

Net unrealized appreciation........................................ $ 7,733,886

</TABLE>

4. Repurchase Agreements

The Fund purchases (and its custodian takes possession of) U.S. government
securities from banks and securities dealers subject to agreements to resell
the securities to the seller at a future date (generally, the next business
day) at an agreed-upon higher repurchase price. The Fund requires maintenance
of the market value of the collateral in amounts at least equal to the
repurchase price.

5. Options Contracts

The Fund may from time to time enter into options contracts. Premiums paid when
put or call options are purchased by the Fund, represent investments, which are
marked-to-market daily. When a purchased option expires, the Fund will realize
a loss in the amount of the premium paid. When the Fund enters into a closing
sales transaction, the Fund will realize a gain or loss depending on whether
the proceeds from the closing sales transaction are greater or less than the
premium paid for the option. When the Fund exercises a put option, it will
realize a gain or loss from the sale of the underlying security and the
proceeds from such sale will be decreased by the premium originally paid. When
the Fund exercises a call option, the cost of the security which the Fund
purchases upon exercise will be increased by the premium originally paid.

At June 30, 2000, the Fund did not hold any purchased options.

                                                                              11
<PAGE>

Notes to Financial Statements
(unaudited) (continued)


When the Fund writes a call or put option, an amount equal to the premium
received by the Fund is recorded as a liability, the value of which is marked-
to-market daily. When a written option expires, the Fund realizes a gain equal
to the amount of the premium received. When the Fund enters into a closing
purchase transaction, the Fund realizes a gain or loss depending upon whether
the cost of the closing transaction is greater or less than the premium
originally received, without regard to any unrealized gain or loss on the
underlying security, and the liability related to such option is eliminated.
When a written call option is exercised the proceeds of the security sold will
be increased by the premium originally received. When a written put option is
exercised, the amount of the premium originally received will reduce the cost
of the security which the Fund purchased upon exercise. When written index
options are exercised, settlement is made in cash.

The Fund enters into options for hedging purposes. The risk associated with
purchasing options is limited to the premium originally paid. The risk in
writing a covered call option is that the Fund gives up the opportunity to
participate in any increase in the price of the underlying security beyond the
exercise price. The risk in writing a put option is that the Fund is exposed to
the risk of loss if the market price of the underlying security declines.

The following written call option transactions occurred during the six months
ended June 30, 2000:

</TABLE>

6. Securities Traded on a When Issued Basis

The Fund may from time to time purchase securities on a when-issued basis. In a
when-issued transaction, the Fund commits to purchasing securities which have
not yet been issued by the issuer. Securities purchased on a when-issued basis,
are not settled until they are delivered to the Fund. Beginning on the date the
Fund enters into the when-issued transaction, cash or other liquid securities
are segregated to cover the amount of the purchase price of the when-issued
security. These transactions are subject to market fluctuations and their
current value is determined in the same manner as for other securities.

At June 30, 2000, the Fund did not hold any when-issued securities.

7. Securities Traded on a To-Be-Announced Basis

The Fund may trade securities on a to-be-announced ("TBA") basis. In a TBA
transaction, the Fund commits to purchasing or selling securities for which
specific information is not yet known at the time of the trade, particularly
the face amount and maturity date in Government National Mortgage Association
("GNMA") transactions. Securities purchased on a TBA basis are not settled
until they are delivered to the Fund, normally 15 to 45 days later. Beginning
on the date the Fund enters into a TBA transaction, cash or other liquid
securities are segregated in the amount of the TBA transaction. These
transactions are subject to market fluctuations and their current value is
determined in the same manner as for other securities.

At June 30, 2000, the Fund did not hold any TBA securities.

8. Lending of Securities

The Fund may lend its securities to brokers, dealers and other financial
organizations. The Fund has an agreement with its custodian whereby the
custodian may lend securities owned by the Fund to brokers, dealers and other
financial organizations. Fees earned by the Fund on securities lending are
recorded in interest income. Loans of securities by the Fund are collateralized
by cash or other liquid securities that are maintained at all times in an
amount at least equal to the current market value of the loaned securities,
plus a margin which may vary depending on the type of securities loaned. The
custodian establishes and maintains the collateral in a segregated account. The
Fund maintains exposure for the risk of any losses in the investment of amounts
received as collateral.

At June 30, 2000, the Fund did not have any securities on loan.

9. Capital Loss Carryforward

At December 31, 1999, the Fund had, for Federal income tax purposes, a capital
loss carryforward of approximately $97,000, available to offset future capital
gains through December 31, 2007. To the extent that these carryforward losses
can be used to offset net realized capital gains, such gains, if any, will not
be distributed.

10. Capital Stock

At June 30, 2000, the Series had 10,000,000,000 shares of capital stock
authorized with a par value of $0.001 per share. Each share represents an equal
proportionate interest and has an equal entitlement to any dividends and
distributions made by the Fund.

Transactions in shares were as follows:

Our Message to You

DEAR SHAREHOLDER:

We are pleased to provide you with the semi-annual report for the Salomon
Brothers Variable Capital Fund ("Fund") for the period ended June 30, 2000. This
letter discusses general economic and market conditions as well as Fund
highlights during the reporting period. A detailed summary of performance and
current Fund holdings can be found in the appropriate sections that follow. We
hope you find this report useful and informative.

INVESTMENT STRATEGY AND PERFORMANCE UPDATE

The Fund seeks capital appreciation through investments primarily in common
stocks or securities convertible into common stocks. The Fund seeks to achieve
its investment objective through investments in securities that are believed to
have above-average price appreciation potential. The Fund invests primarily in
stocks of U.S. companies. These companies may range in size from established
large capitalization companies (over $5 billion in market capitalization) to
small capitalization companies (i.e., less than $1 billion in market
capitalization) at the beginning of their life cycles. Such investments may also
involve above-average risk. The Fund may invest in seasoned, established
companies, relatively small new companies, as well as new issues.

The Fund's shares returned 16.47% for the six-month period ended June 30, 2000.
In comparison, the Russell 3000 Index returned 0.95% and the Standard and Poor's
500 Index ("S&P 500") declined 0.43% for the same time period. (The S&P 500 is a
market capitalization-weighted measure of 500 widely held common stocks. The
Russell 3000 Index measures the performance of the 3,000 largest U.S. companies
based on total market capitalization, which represents approximately 98% of the
investable U.S. equity market.)

The Fund's investment strategy is known as a broad market strategy. We attempt
to find the best opportunities across the market, wherever they may be. It is an
"all cap" or "multicap" strategy in that we invest in large-, small- and
mid-size companies. Our strategy can also be characterized as a "style neutral"
or "blend" portfolio in that we purchase both growth and value stocks. (Value
investing consists of identifying securities of companies that are believed to
be undervalued in the market. Growth investing focuses on the stocks of
corporations that are exhibiting or are expected to exhibit faster-than-average
growth within their industry.) In fact, one of our primary goals is to find out
of favor value stocks that blossom into growth stocks. These can sometimes
include some of our best performers because we buy them when they are
inexpensive and hold them through the entire period of appreciation as the
market recognizes their true potential.

                                                                               1
<PAGE>

Because the Fund owns some stocks from most categories, the Fund has the
opportunity to own some promising securities under most market conditions and
our strategy can result in a unique, diversified portfolio of stocks. We think
that these are two key advantages to our investment strategy.1

Our core investment style is a bottom-up stock picking strategy. (Bottom-up
investing is an asset management style that focuses on the analysis of
individual stocks instead of basing decisions on economic or market trends.) We
focus on understanding a company's business, its strategy, its competitive
position and its industry. We also determine if management is credible and has
the right team to lead the company. Our financial analysis focuses on the
company's resources to meet its goals, the consistency of the numbers to
determine their quality (for instance, are receivables growing much faster than
sales?, a sign that current sales may overstate the long term trend) and is used
as a framework for valuation and risk assessment. These and other factors are
what drive our stock selection process. If we think that the risk and reward
trade-off for a particular company's stock is favorable, we will generally
invest.

As portfolio managers, we have a role in addition to stock picking; we need to
put all the individual security selections into a portfolio that meets a set of
investment objectives. We use tools such as diversification and position
weighting to determine exactly how much of each security to own in the
portfolio. For instance, in the Fund, our best ideas generally get very high
weightings, as much as 5% of the portfolio on occasion. This strategy, known as
high position concentration, can generate above-market return potential if
executed properly. (Of course, past performance is not indicative of future
results.)

At the same time, we always factor in excess risk. A good idea that has a very
high-risk profile tends to get lower weighting, such as 1% of the portfolio, in
order to diversify risk and dampen portfolio volatility. And while no guarantees
can be made, this way we can take individual risks on behalf of our shareholders
without creating an overly risky portfolio.


----------------
1 Of course, investors can also lose money in the sub-account if our judgement
  about the attractiveness, relative value or potential appreciation of a
  particular sector or security proves to be incorrect.

MARKET OVERVIEW AND OUTLOOK

Even though it made no headway, the stock market offered something for everyone
during the first half of 2000. Initially the speculative momentum market of 1999
helped the market rally continue, peaking during the second week of March. The
Federal Reserve Board's ("Fed") continued increases in interest rates then
started to be felt, leading to a violent sell-off, particularly in the volatile
NASDAQ market, through May. At the same time, many oversold "Old Economy" stocks
rallied as money rotated from the Internet and biotech stocks into areas such as
consumer staples. By the end of the half, most of the market losses were
recovered so that most broad indices were down modestly.

One way to describe what happened is that "investment gravity" finally took hold
of stocks that previously seemed to continually float skyward. The catalyst was
the seemingly unrelated comments by U.S. President Bill Clinton and British
Prime Minister Tony Blair that genomics companies would not reap all of the
benefits of the public research money devoted to their field of science. The
sell-off in biotech stocks spread like contagion to all high-priced growth
stocks. For a relatively brief time, earnings counted and stories were
discounted. By the end of June, the market was once again awarding future
potential a premium to proven ability.

The Fund's investment strategy worked exceptionally well throughout the
six-month period. When the market was rising our broad, diversified equity
exposure allowed us to participate even though much of what we liked was out of
favor. The declines in less speculative stocks provided us with opportunities as
well. For the first time in over two years, we were given an attractive
opportunity to start building positions in drug stocks, a sector that we think
should exhibit above-average growth well into the future due to favorable
demographic and technological trends.

Later in the half, during the NASDAQ-led market decline, the Fund actually
appreciated as money flowed to companies that could be more easily valued, most
of which had been materially oversold in the previous few months. The rotation
favored drug stocks as well as companies we previously owned such as Safeway,
Nabisco Group Holdings and Devon Energy while giving us the opportunity to add
to undervalued technology stocks like 3Com and Seagate. Going forward, we expect
to continue to hold many of these stocks although there have been tender offers
announced for Nabisco and Seagate.

                                                                               3
<PAGE>

We continue to see the growth of the Internet as one of the driving forces of
the economy going forward. If you closely examine the Fund's portfolio, you will
see that relatively little of your money is invested in traditional Internet
companies (i.e., the "dot.coms"). We think the long-term risk and reward
proposition in most of these companies to be unattractive, a view we think the
market is starting to embrace. We also think most of these companies do not have
sustainable business models (translation: in our opinion they will always lose
money), while others have valuations that assume they will be the only survivors
in the eventual shakeout. However, you will see a lot of your money invested in
companies that benefit from or build the Internet. In the Fund we own companies
such as...

 .   3Com (a company that split into two pieces in July; Palm Pilot, the leading
    PDA which will offer wireless internet access, and the remaining 3Com
    networking business helping individuals access the Internet);

 .   Federated Department Stores (a leader in the "clicks and mortar" e-commerce
    strategy and owner of several valuable Internet businesses); and

 .   Verizon (formed from the merger of Bell Atlantic and GTE, Verizon is the
    leading U.S. wireless company also offering telecom services such as local,
    long distance and high-speed Internet access).

It is our strong belief that over time the leading established companies that
embrace today's new technologies should emerge as the dominant and most
profitable companies in the economy. Their stocks should recognize this over
time. On the other hand, we believe the stock market will continue to lose
patience with those traditional Internet companies that cannot transform
themselves into growth companies with enough profits to support their stock
price.

We expect the Fund to consistently apply its investment strategy in the future.
We will invest in both users and manufacturers of technology when we believe
their risk reward ratios are favorable. Most of all, we will look for the best
opportunities that we can find, regardless of the part of the market they
currently reside in.

     at net asset value. Total returns do not reflect expenses associated with
     the separate account such as administrative fees, account charges and
     surrender charges which, if reflected, would reduce the total returns for
     all periods shown. Total returns may also reflect a voluntary expense cap
     imposed by Salomon Brothers Asset Management Inc to limit total Fund
     operating expenses. Absent this expense cap, total returns for the Fund
     would be lower. Expense caps may be revised or terminated.
++   Total return is not annualized, as it may not be representative of the
     total return for the year.

1. Organization and Significant Accounting Policies

Salomon Brothers Variable Capital Fund ("Fund") is a separate non-diversified
investment portfolio of the Salomon Brothers Variable Series Funds Inc
("Series") whose primary investment objective is to seek capital appreciation.
The Series, a Maryland corporation, is registered under the Investment Company
Act of 1940, as amended ("1940 Act"), as an open-end management investment
company and consists of this Fund and seven other investment portfolios:
Salomon Brothers Variable Small Cap Growth Fund, Salomon Brothers Variable
Total Return Fund, Salomon Brothers Variable High Yield Bond Fund, Salomon
Brothers Variable Investors Fund, Salomon Brothers Variable Strategic Bond
Fund, Salomon Brothers Variable U.S. Government Income Fund and Salomon
Brothers Variable Asia Growth Fund. The U.S. Government Income Fund and Asia
Growth Fund have not yet commenced operations. The financial statements and
financial highlights for the other investment portfolios are presented in
separate shareholder reports. The Fund and each other investment portfolio of
the Series is offered exclusively for use with certain variable annuity and
variable life insurance contracts offered through the separate accounts of
various life insurance companies and qualified pension and retirement plans.

The significant accounting policies consistently followed by the Fund are: (a)
security transactions are accounted for on trade date; (b) securities traded on
national securities markets are valued at the closing prices on such markets;
securities traded in the over-the-counter market and securities for which no
sales price was reported are valued at the mean of the current bid and asked
prices; debt securities are valued using either prices or estimates of market
values provided by market makers or independent pricing services; securities
and assets for which market quotations are not readily available are valued at
fair value as determined in good faith by or under the direction of the Board
of Directors of the Fund; (c) securities maturing within 60 days are valued at
cost plus accreted discount, or minus amortized premium, which approximates
market value; (d) dividend income is recorded on the ex-dividend date; (e)
interest income, adjusted for accretion of original issue or market discount,
is recorded on the accrual basis; (f) gains or losses on the sale of securities
are calculated by using the specific identification method; (g) dividends and
distributions to shareholders are recorded on the ex-dividend date; (h) the
accounting records are maintained in U.S. dollars. All assets and liabilities
denominated in foreign currencies are translated into U.S. dollars based on the
rate of exchange of such currencies against U.S. dollars on the date of
valuation. Purchases and sales of securities, and income and expenses are
translated at the rate of exchange quoted on the respective date that such
transactions are recorded. Differences between income and expense amounts
recorded and collected or paid are recorded as currency gains or losses (i) the
character of income and gains to be distributed are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles; (j) the Fund intends to comply with the applicable provisions of
the Internal Revenue Code of 1986, as amended, pertaining to regulated
investment companies and to make distributions of taxable income sufficient to
relieve the Fund from substantially all Federal income and excise taxes; and
(k) estimates and assumptions are required to be made regarding assets,
liabilities and changes in net assets resulting from operations when financial
statements are prepared. Changes in the economic environment, financial markets
and any other parameters used in determining these estimates could cause actual
results to differ.

Organization costs amounting to $31,250 were incurred with the organization of
the Fund. These costs are being amortized ratably over a five-year period from
commencement of operations.

2. Management Agreement and Transactions with Affiliated Persons

Salomon Brothers Asset Management Inc ("SBAM"), a wholly owned subsidiary of
Salomon Brothers Holding Company Inc., which, in turn, is wholly owned by
Salomon Smith Barney Holdings, Inc. ("SSBH"), acts as investment manager to the
Fund. Under the investment management agreement, the Fund pays an investment
management fee calculated at the annual rate of 0.85% of its average daily net
assets. This fee is calculated daily and paid monthly.

For the six months ended June 30, 2000, SBAM waived a portion of the management
fees payable by the Fund amounting to $28,692.

                                                                              13

the Fund pays SBAM a fee calculated at an annual rate of 0.05% of its average
daily net assets. This fee is calculated daily and paid monthly. SBAM has
delegated its responsibilities as administrator to SSB Citi Fund Management LLC
("SSBC"), an affiliate of SBAM, pursuant to a Sub-Administration Agreement
between SBAM and SSBC.

CFBDS, Inc. acts as the Fund's distributor. For the six months ended June 30,
2000, Salomon Smith Barney Inc. ("SSB"), another subsidiary of SSBH, received
brokerage commissions of $54 from the Fund.

3. Investments

During the six months ended June 30, 2000, the aggregate cost of purchases and

</TABLE>

4. Repurchase Agreements

The Fund purchases (and its custodian takes possession of) U.S. government se-
curities from banks and securities dealers subject to agreements to resell the
securities to the seller at a future date (generally, the next business day) at
an agreed-upon higher repurchase price. The Fund requires maintenance of the
market value of the collateral in amounts at least equal to the repurchase
price.

5. Options Contracts

The Fund may from time to time enter into options contracts. Premiums paid when
put or call options are purchased by the Fund, represent investments, which are
marked-to-market daily. When a purchased option expires, the Fund will realize
a loss in the amount of the premium paid. When the Fund enters into a closing
sales transaction, the Fund will realize a gain or loss depending on whether
the proceeds from the closing sales transaction are greater or less than the
premium paid for the option. When the Fund exercises a put option, it will re-
alize a gain or loss from the sale of the underlying security and the proceeds
from such sale will be decreased by the premium originally paid. When the Fund
exercises a call option, the cost of the security which the Fund purchases upon
exercise will be increased by the premium originally paid.

At June 30, 2000, the Fund had purchased put options with a total cost of
$103,067.

Notes to Financial Statements
(unaudited) (continued)

When the Fund writes a call or put option, an amount equal to the premium re-
ceived by the Fund is recorded as a liability, the value of which is marked-to-
market daily. When a written option expires, the Fund realizes a gain equal to
the amount of the premium received. When the Fund enters into a closing pur-
chase transaction, the Fund realizes a gain or loss depending upon whether the
cost of the closing transaction is greater or less than the premium originally
received, without regard to any unrealized gain or loss on the underlying secu-
rity, and the liability related to such option is eliminated. When a written
call option is exercised the proceeds of the security sold will be increased by
the premium originally received. When a written put option is exercised, the
amount of the premium originally received will reduce the cost of the security
which the Fund purchased upon exercise. When written index options are exer-
cised, settlement is made in cash.

The Fund enters into options for hedging purposes. The risk associated with
purchasing options is limited to the premium originally paid. The risk in
writing a covered call option is that the Fund gives up the opportunity to
participate in any increase in the price of the underlying security beyond the
exercise price. The risk in writing a put option is that the Fund is exposed to
the risk of loss if the market price of the underlying security declines.

The following written put option transactions occurred during the six months
ended June 30, 2000:

6. Securities Traded on a When Issued Basis

The Fund may from time to time purchase securities on a when-issued basis. In a
when-issued transaction, the Fund commits to purchasing securities which have
not yet been issued by the issuer. Securities purchased on a when-issued basis,
are not settled until they are delivered to the Fund. Beginning on the date the
Fund enters into the when-issued transaction, cash and other liquid securities
are segregated to cover the amount of the purchase price of the when-issued
security. These transactions are subject to market fluctuations and their
current value is determined in the same manner as for other securities.

At June 30, 2000 the Fund did not hold any when-issued securities.

7. Securities Traded on a To-Be-Announced Basis

The Fund may trade securities on a to-be-announced ("TBA") basis. In a TBA
transaction, the Fund commits to purchasing or selling securities for which
specific information is not yet known at the time of the trade, particularly
the face amount and maturity date in Government National Mortgage Association
("GNMA") transactions. Securities purchased on a TBA basis are not settled
until they are delivered to the Fund, normally 15 to 45 days later. Beginning
on the date the Fund enters into a TBA transaction, cash or other liquid
securities are segregated to cover the amount of the TBA transaction. These
transactions are subject to market fluctuations and their current value is
determined in the same manner as for other securities.

At June 30, 2000, the Fund did not hold any TBA securities.

                                                                              15

8. Lending of Securities

The Fund may lend its securities to brokers, dealers and other financial
organizations. The Fund has an agreement with its custodian whereby the
custodian may lend securities owned by the Fund to brokers, dealers and other
financial organizations. Fees earned by the Fund on securities lending are
recorded in interest income. Loans of securities by the Fund are collateralized
by cash and other liquid securities that are maintained at all times in an
amount at least equal to the current market value of the loaned securities,
plus a margin which may vary depending on the type of securities loaned. The
custodian establishes and maintains the collateral in a segregated account. The
Fund maintains exposure for the risk of any losses in the investment of amounts
received as collateral.

At June 30, 2000 the Fund did not have any securities on loan.

9. Capital Stock

At June 30, 2000 the Series had 10,000,000,000 shares of capital stock autho-
rized with a par value of $0.001 per share. Each share represents an equal pro-
portionate interest and has an equal entitlement to any dividends and distribu-
tions made by the Fund.

Transactions in shares were as follows:

Our Message to You


Dear Shareholder:

We are pleased to provide the semi-annual report for the Salomon Brothers
Variable Total Return Fund ("Fund") for the period ended June 30, 2000. This
letter discusses general economic and market conditions as well as major Fund
developments during the reporting period. A detailed summary of performance and
current Fund holdings can be found in the appropriate sections that follow. We
hope you find this report to be useful and informative.

Investment Strategy and Performance Update

The Fund seeks to obtain above-average income compared to a portfolio that
invests only in stocks. The Fund's secondary objective is to take advantage of
opportunities for growth of capital and income by investing in a variety of
asset classes including stocks, bonds and short-term obligations. For the six
months ended June 30, 2000, the Fund generated a return of 3.13%. In comparison,
the Standard & Poor's 500 Index ("S&P 500")(1) returned a negative 0.43% for the
period. In addition, a return for a hypothetical Index consisting of a 50%
weighting of the Salomon Smith Barney Broad Investment Grade ("BIG") Bond
Index(2) and 50% weighting of the S&P 500(3) returned 1.87% for the same time
period. (Please note that an investor cannot invest directly in an index.)

Market Update and Outlook

In the first half of 2000, the common stock sector continued to emphasize high
quality companies in growth industries including communications, pharmaceutical,
energy, consumer brands and technology. The fixed-income segment represents
approximately 50% of the portfolio in order to reduce overall risk and provide
added income potential.

As the Federal Reserve Board ("Fed") moves to slow the economy, we anticipate
moderate growth in the U.S. and continuing improvement in most of the major
overseas countries. Earnings for U.S. companies should be restrained somewhat
during the coming year.

_________________
1 The S&P 500 is a market capitalization-weighted measure of 500 widely held
  common stocks.

2 The Salomon Smith Barney BIG Bond Index includes institutionally traded U.S.
  Treasury bonds, government-sponsored bonds (U.S. Agency and supranational),
  mortgage-backed securities and corporate securities.

3 The 50% Salomon Smith Barney BIG Bond Index and 50% S&P 500 consists of
  domestic corporate, government and agency securities and 500 widely held
  common stocks.

                                                                               1

In a period of economic growth, the common stock portfolio is being positioned
in companies with financial strength and in areas where we believe product
demand will be firm. As of June 30, 2000, the largest holdings of common stock,
in order of size were IBM, Pfizer, Coca-Cola, Anheuser-Busch, Merck, McDonald's,
Johnson & Johnson and General Electric. Please keep in mind, portfolio holdings
are subject to change.

Thank you for your investment in the Salomon Brothers Variable Total Return
Fund. We look forward to helping you pursue your financial goals in the new
century.

Sincerely,


/s/ Heath B. McLendon           /s/ George J. Williamson

+     Assumes the reinvestment of all dividends and capital gains distributions
      at net asset value. Total returns do not reflect expenses associated with
      the separate account such as administrative fees, account charges and
      surrender charges which, if reflected, would reduce the total returns for
      all periods shown. Total returns may also reflect a voluntary expense cap
      imposed by Salomon Brothers Asset Management Inc to limit total Fund
      operating expenses. Absent this expense cap, total returns for the Fund
      would be lower. Expense caps may be revised or terminated.

++    Total return is not annualized, as it may not be representative of the
      total return for the year.

1. Organization and Significant Accounting Policies

Salomon Brothers Variable Total Return Fund ("Fund") is a separate diversified
investment portfolio of the Salomon Brothers Variable Series Funds Inc
("Series") whose primary investment objective is to obtain above-average income
(as compared to a portfolio entirely invested in equity securities). The
Series, a Maryland corporation, is registered under the Investment Company Act
of 1940, as amended ("1940 Act"), as an open-end management investment company
and consists of this Fund and seven other investment portfolios: Salomon
Brothers Variable Capital Fund, Salomon Brothers Variable High Yield Bond Fund,
Salomon Brothers Variable Investors Fund, Salomon Brothers Variable Strategic
Bond Fund, Salomon Brothers Variable Small Cap Growth Fund, Salomon Brothers
Variable U.S. Government Income Fund and Salomon Brothers Variable Asia Growth
Fund. The U.S. Government Income Fund and Asia Growth Fund have not yet
commenced operations. The financial statements and financial highlights for the
other investment portfolios are presented in separate shareholder reports. The
Fund and each other investment portfolio of the Series is offered exclusively
for use with certain variable annuity and variable life insurance contracts
offered through the separate accounts of various life insurance companies and
qualified pension and retirement plans.

The significant accounting policies consistently followed by the Fund are: (a)
security transactions are accounted for on trade date; (b) securities traded on
national securities markets are valued at the closing prices on such markets;
securities traded in the over-the-counter market and securities for which no
sales price was reported are valued at the mean of the bid and asked prices;
debt securities are valued using either prices or estimates of market values
provided by market markers or independent pricing services; securities and
assets for which market quotations are not readily available are valued at fair
value as determined in good faith by or under the direction of the Board of
Directors of the Fund; (c) securities maturing within 60 days are valued at
cost plus accreted discount, or minus amortized premium, which approximates
market value; (d) dividend income is recorded on the ex-dividend date; (e)
interest income, adjusted for accretion of original issue and market discount,
is recorded on the accrual basis; (f) gains or losses on the sale of securities
are calculated by using the specific identification method; (g) dividends and
distributions to shareholders are recorded on the ex-dividend date; (h) the
accounting records are maintained in U.S. dollars. All assets and liabilities
denominated in foreign currencies are translated into U.S. dollars based on the
rate of exchange of such currencies against U.S. dollars on the date of
valuation. Purchases and sales of securities, and income and expenses are
translated at the rate of exchange quoted on the respective date that such
transactions are recorded. Differences between income and expense amounts
recorded and collected or paid are recorded as currency gains or losses; (i)
the character of income and gains to be distributed are determined in
accordance with income tax regulations which may differ from generally accepted
accounting principles. At December 31, 1999, reclassifications were made to the
capital accounts of the Fund to reflect permanent book/tax differences and
income and gains available for distributions under income tax regulations. Net
investment income, net realized gains and net assets were not affected by this
change; (j) the Fund intends to comply with the applicable provisions of the
Internal Revenue Code of 1986, as amended, pertaining to regulated investment
companies and to make distributions of taxable income sufficient to relieve the
Fund from substantially all Federal income and excise taxes; and (k) estimates
and assumptions are required to be made regarding assets, liabilities and
changes in net assets resulting from operations when financial statements are
prepared. Changes in the economic environment, financial markets and any other
parameters used in determining these estimates could cause actual results to
differ.

Organization costs amounting to $31,250 were incurred with the organization of
the Fund. These costs are being amortized ratably over a five year period from
commencement of operations.

2. Management Agreement and Transactions with Affiliated Persons

Salomon Brothers Asset Management Inc ("SBAM"), a wholly owned subsidiary of
Salomon Brothers Holding Company Inc., which in turn is wholly owned by Salomon
Smith Barney Holdings, Inc. ("SSBH"), acts as investment manager to the Fund.
Under the investment management agreement, the Fund pays an investment
management fee calculated at the annual rate of 0.80% of its average daily net
assets. This fee is calculated daily and paid monthly.

For the six months ended June 30, 2000, SBAM waived a portion of its management
fees amounting to $28,165.

                                                                              11
<PAGE>

SBAM also acts as administrator to the Fund. As compensation for its services
the Fund pays SBAM a fee calculated at an annual rate of 0.05% of its average
daily net assets. This fee is calculated daily and paid monthly. SBAM has dele-
gated its responsibilities as administrator to SSB Citi Fund Management LLC
("SSBC"), an affiliate of SBAM, pursuant to a Sub-Administration Agreement be-
tween SBAM and SSBC.

CFBDS, Inc. acts as the Fund's distributor. For the six months ended June 30,
2000, Salomon Smith Barney Inc., another subsidiary of SSBH, did not receive
any brokerage commissions from the Fund.

3. Investments

During the six months ended June 30, 2000, the aggregate cost of purchases and
proceeds from sales of investments (including maturities, but excluding short-
term securities) were as follows:

<TABLE>
<S>                                                                <C>

  U.S. government agencies & obligations.......................... $   476,712
  Other investment securities.....................................   3,431,077
                                                                   -----------
                                                                   $ 3,907,789
                                                                   ===========
Sales:
  U.S. government agencies & obligations.......................... $   178,488
  Other investment securities.....................................   3,552,138
                                                                   -----------
                                                                   $ 3,730,626

At June 30, 2000, the aggregate gross unrealized appreciation and depreciation
of investments for Federal income tax purposes were substantially as follows:

Gross unrealized appreciation..................................... $ 1,166,375
Gross unrealized depreciation.....................................  (1,291,499)
                                                                   -----------
Net unrealized depreciation....................................... $  (125,124)
                                                                   ===========
</TABLE>

4. Repurchase Agreements

The Fund purchases (and its custodian takes possession of) U.S. government se-
curities from banks and securities dealers subject to agreements to resell the
securities to the seller at a future date (generally, the next business day) at
an agreed-upon higher repurchase price. The Fund requires maintenance of the
market value of the collateral in amounts at least equal to the repurchase
price.

5. Reverse Repurchase Agreements

The Fund may enter into reverse repurchase agreements. A reverse repurchase
agreement involves a sale by the Fund of securities that it holds with an
agreement by the Fund to repurchase the same securities at an agreed upon price
and date. A reverse repurchase agreement involves risk that the market value of
the securities sold by the Fund may decline below the repurchase price of the
securities. The Fund will segregate cash or other liquid securities with re-
spect to the reverse repurchase agreements.

During the six months ended June 30, 2000, the Fund did not enter into any re-
verse repurchase agreements.

6. Options Contracts

The Fund may from time to time enter into options contracts. Premiums paid when
put or call options are purchased by the Fund, represent investments, which are
marked-to-market daily. When a purchased option expires, the Fund will realize
a loss in the amount of the premium paid. When the Fund enters into a closing
sales transaction, the Fund will realize a gain or loss depending on whether
the proceeds from the closing sales transaction are greater or less than the
premium paid for the option. When the Fund exercises a put option, it will re-
alize a gain or loss from the sale of the underlying security and the proceeds
from such sale will be decreased by the premium originally paid. When the Fund
exercises a call option, the cost of the security which the Fund purchases upon
exercise will be increased by the premium originally paid.

At June 30, 2000, the Fund did not have any open purchased call or put option
contracts.

When the Fund writes a call or put option, an amount equal to the premium re-
ceived by the Fund is recorded as a liability, the value of which is marked-to-
market daily. When a written option expires, the Fund realizes a gain equal to
the amount of the premium received. When the Fund enters into a closing pur-
chase transaction, the Fund realizes a gain or loss depending upon whether the
cost of the closing transaction is greater or less than the premium originally
received, without regard to any unrealized gain or loss on the underlying secu-
rity, and the liability related to such option is eliminated. When a written
call option is exercised the proceeds of the security sold will be increased by
the premium originally received. When a written put option is exercised, the
amount of the premium originally received will reduce the cost of the security
which the Fund purchased upon exercise. When written index options are exer-
cised, settlement is made in cash.

The Fund enters into options for hedging purposes. The risk associated with
purchasing options is limited to the premium originally paid. The risk in writ-
ing a covered call option is that the Fund gives up the opportunity to partici-
pate in any increase in the price of the underlying security beyond the exer-
cise price. The risk in writing a put option is that the Fund is exposed to the
risk of loss if the market price of the underlying security declines.

During the six months ended June 30, 2000, the Fund did not write any call or
put option contracts.

7. Securities Traded on a When-Issued Basis

The Fund may from time to time purchase securities on a when-issued basis. In a
when-issued transaction, the Fund commits to purchasing securities which have
not yet been issued by the issuer. Securities purchased on a when-issued basis,
are not settled until they are delivered to the Fund. Beginning on the date the
Fund enters into the when-issued transaction, cash or other liquid securities
are segregated to cover the amount of the purchase price of the when-issued
security. These transactions are subject to market fluctuations and their
current value is determined in the same manner as for other securities.

At June 30, 2000, the Fund did not hold any when-issued securities.

8. Securities Traded on a To-Be-Announced Basis

The Fund may trade securities on a to-be-announced ("TBA") basis. In a TBA
transaction, the Fund commits to purchasing or selling securities which have
not yet been issued by the issuer, particularly the face amount and maturity
date in Government National Mortgage Association ("GNMA") transactions.
Securities purchased on a TBA basis are not settled until they are delivered to
the Fund, normally 15 to 45 days later. Beginning on the date the Fund enters
into a TBA transaction, cash or other liquid securities are segregated to cover
the amount of the TBA transaction. These transactions are subject to market
fluctuations and their current value is determined in the same manner as for
other securities.

At June 30, 2000, the Fund held TBA securities with a total cost of $1,713,049.

                                                                              13

9. Mortgage Dollar Roll Transactions

The Fund may enter into mortgage "dollar rolls" in which the Fund sells
mortgage-backed securities for delivery in the current month and simultaneously
contracts to repurchase substantially similar (same type, coupon and maturity)
securities on a specific future date. The Fund is compensated by a fee paid by
the counterparty. Dollar rolls are accounted for as financing arrangements; the
fee is accrued into interest income ratably over the term of the dollar roll
and any gain or loss on the roll is deferred until disposition of the rolled
security. The average daily balance of dollar rolls outstanding during the six
months ended June 30, 2000 was approximately $1,804,000.

10. Lending of Securities

The Fund may lend its securities to brokers, dealers and other financial
organizations. The Fund has an agreement with its custodian whereby the
custodian may lend securities owned by the Fund to brokers, dealers and other
financial organizations. Fees earned by the Fund on securities lending are
recorded in interest income. Loans of securities by the Fund are collateralized
by cash or other liquid securities that are maintained at all times in an
amount at least equal to the current market value of the loaned securities,
plus a margin which may vary depending on the type of securities loaned. The
custodian establishes and maintains the collateral in a segregated account. The
Fund maintains exposure for the risk of any losses in the investment of amounts
received as collateral.

At June 30, 2000, the Fund did not have any securities on loan.

11. Loan Participations

The Fund may invest in loans arranged through private negotiation between one
or more financial institutions. The Fund's investment in any such loan may be
in the form of a participation in or an assignment of the loan.

In connection with purchasing participations, the Fund generally will have no
right to enforce compliance by the borrower with the terms of the loan
agreement relating to the loan, nor any rights of set-off against the borrower,
and the Fund may not benefit directly from any collateral supporting the loan
in which it has purchased the participation. As a result, the Fund will assume
the credit risk of both the borrower and the lender that is selling the
participation. In the event of the insolvency of the lender selling the
participation, the Fund may be treated as a general creditor of the lender and
may not benefit from any set-off between the lender and the borrower.

At June 30, 2000, the Fund did not have any investments in loan participations.

12. Capital Loss Carryforward

At December 31, 1999, the Fund had, for Federal income tax purposes, a capital
loss carryforward of approximately $12,300, available to offset future capital
gains through December 31, 2007. To the extent that these carryforward losses
are used to offset capital gains, it is probable that the gains so offset will
not be distributed.

13. Capital Stock

At June 30, 2000, the Series had 10,000,000,000 shares of capital stock autho-
rized with a par value of $0.001 per share. Each share represents an equal pro-
portionate interest and has an equal entitlement to any dividends and distribu-
tions made by the Fund.

Transactions in shares were as follows:

(4) Total returns do not reflect expenses associated with the separate account
    such as administrative fees, account charges and surrender charges which,
    if reflected, would reduce the total returns for all periods shown. Total
    returns may also reflect a voluntary expense cap imposed by Salomon Broth-

    this expense cap, total returns for the Fund would be lower. Expense caps
    may be revised or terminated.

SALOMON BROTHERS VARIABLE SERIES FUNDS INC
Our Message to You

DEAR SHAREHOLDER:
We are pleased to provide you with the semi-annual report for the Salomon
Brothers Variable High Yield Bond Fund ("Fund") for the period ended June 30,
2000. This letter will briefly discuss general economic and market conditions as
well as Fund developments during the reporting period.1 A detailed summary of
performance and current Fund holdings can be found in the appropriate sections
that follow. We hope you find this report useful and informative.

INVESTMENT STRATEGY AND PORTFOLIO UPDATE
The Fund's primary objective is to maximize current income, with capital
appreciation as a secondary objective. The Fund seeks to achieve its objectives
by investing primarily in a diversified portfolio of high-yield fixed-income
securities rated in the medium or lower rating categories or those securities
determined by the manager to be of comparable quality. For the six months ended
June 30, 2000, the Fund returned a negative 0.54% versus a negative 1.42% return
for the Salomon Smith Barney High Yield Market Index2 over the same period.

MARKET OVERVIEW
For the six months ended June 30, 2000, the high-yield bond market returned
negative 1.42% as reported by the Salomon Smith Barney High Yield Market Index.
Interest rate and inflation concerns were serious issues for the high-yield bond
market throughout the period.

As the Federal Reserve Board ("Fed") hiked interest rates by 25 basis points3 in
February and the tech-laden Nasdaq Composite Index4 turned in a relatively
strong performance early in calendar year 2000, a string of mutual fund outflows
ensued as investors fled the interest rate-sensitive bond markets for the strong
stock markets. As the U.S. stock markets became more volatile in March and April
and the Fed announced a 50 basis point interest rate increase with a tightening
bias on May 16, 2000, mutual fund outflows intensified as investors focused on
the potential for further interest rate increases. Investors also increasingly
considered the possibility of a cyclical downturn in the near term, which would
exacerbate already high default rates.

-------------------
1    The information provided represents the opinion of the manager and is not
     intended to be a forecast of future results. Further, there is no assurance
     that certain securities will remain in or out of the portfolio.
2    The Salomon Smith Barney High Yield Market Index covers a significant
     portion of the below-investment-grade U.S. corporate bond market. An
     investor cannot invest directly in an index.
3    A basis point is 0.01% or one one-hundredth of a percent.
4    The Nasdaq Composite Index is a market value-weighted index that measures
     all domestic and non-U.S. based securities listed on the NASDAQ stock
     market. An investor cannot invest directly in an index.

                                                                               1

As a result, mutual fund outflows for the period totaled about $5.9 billion. In
June, however, benign economic data and a more passive Fed mitigated interest
rate concerns while the high absolute yields available in the high-yield bond
market attracted investors from the volatile equity markets. As a result, the
high-yield bond market saw in June its first month of positive mutual fund flows
in 2000 and returned 2.25% for the month, according to the Salomon Smith Barney
High Yield Market Index.

For the six months ended June 30, 2000, the top performing sectors in the
high-yield market included telecommunications, energy, technology, utilities and
gaming. Telecommunications performance was driven by explosive industry growth,
continued mergers and acquisitions and stock investment activity. High product
prices supported positive performance in energy. Technology's performance
benefited from good fourth quarter 1999 results and the popularity of the sector
in the stock markets early in the period. Utilities and gaming, which are
generally composed of higher rated issuers, benefited from investors' preference
for higher-quality issues.

The most significant underperforming sectors consisted of automotive,
steel/metals, capital goods, leisure/lodging, supermarkets/drugstores and
services/other. Automotive was adversely affected by weakness in the parts
aftermarket. Steel/metal's performance was hurt by product price weakness.
Additionally, automotive, steel/metals and capital goods were negatively
impacted by increased cyclical concerns. Leisure/lodging was adversely affected
by operating difficulties at several issuers resulting from overcapacity in the
theatre operator sector. Supermarkets/drugstores performance was adversely
affected by difficulties at Rite Aid and Pathmark.

In terms of credit quality, BB issues outperformed B issues, which in turn
outperformed CCC issues as investors continued to favor the greater liquidity
and higher credit quality offered by BB issues. BB, B and CCC issues returned
0.28%, negative 2.01% and negative 3.92%, respectively.

The Fund benefited from overweightings in energy and gaming. It was also helped
by an underweighting in supermarkets/drugstores. Performance was hurt, however,
by overweightings in steel/metals and capital goods and underweightings in
telecommunications, technology and utilities. During the course of the period,
the Fund responded to market conditions by increasing its positions in energy
and gaming and reducing its positions in steel/metals and leisure/lodging.

On June 30, 2000, the high-yield bond market, as measured by the Salomon Smith
Barney High Yield Market Index, yielded 12.52%, up from 11.41% at year-end 1999.
The excess yield over Treasuries was 6.40%, up from 5.00% at 1999 year-end. We
believe that these levels represent attractive long-term value. (Please note
that past performance is not indicative of future results. Additionally, index
returns are not representative of the Fund's yield.)

Going forward, we expect the high-yield market to continue to experience
volatility over the course of the year primarily as a result of several
technical factors, including:

     .    mutual fund flows;
     .    decreased Collateralized Bond Obligations ("CBO") demand;
     .    reduced secondary market liquidity; and
     .    continuing cyclical concerns.

In light of these conditions, we are pursuing a conservative investment strategy
geared to overweighting BB credits and aggressively pursuing selective
opportunities in undervalued B and CCC credits.

Thank you for your investment in the Salomon Brothers Variable High Yield Bond
Fund. We look forward to helping you pursue your financial goals in the new
century.

Cordially,

/s/Heath B. McLendon                        /s/Peter J. Wilby

1. Organization and Significant Accounting Policies

Salomon Brothers Variable High Yield Bond Fund ("Fund") is a separate
diversified investment portfolio of the Salomon Brothers Variable Series Funds
Inc ("Series") whose primary investment objective is to maximize current income
and secondarily to seek capital appreciation. The Series, a Maryland
corporation, is registered under the Investment Company Act of 1940, as amended
("1940 Act"), as an open-end management investment company and consists of this
Fund and seven other investment portfolios: Salomon Brothers Variable Capital
Fund, Salomon Brothers Variable Small Cap Growth Fund, Salomon Brothers
Variable Total Return Fund, Salomon Brothers Variable Investors Fund, Salomon
Brothers Variable Strategic Bond Fund, Salomon Brothers Variable U.S.
Government Income Fund and Salomon Brothers Variable Asia Growth Fund. The U.S.
Government Income Fund and Asia Growth Fund have not yet commenced operations.
The financial statements and financial highlights for the other investment
portfolios are presented in separate shareholder reports. The Fund and each
other investment portfolio of the Series is offered exclusively for use with
certain variable annuity and variable life insurance contracts offered through
the separate accounts of various life insurance companies and qualified pension
and retirement plans.

The significant accounting policies consistently followed by the Fund are: (a)
security transactions are accounted for on trade date; (b) securities traded on
national securities markets are valued at the closing prices on such markets;
securities traded in the over-the-counter market and securities for which no
sales price was reported are valued at the mean of the current bid and asked
prices; debt securities are valued using either prices or estimates of market
values provided by market makers or independent pricing services; securities
and assets for which market quotations are not readily available are valued at
fair value as determined in good faith by or under the direction of the Board
of Directors of the Fund; (c) securities maturing within 60 days are valued at
cost plus accreted discount, or minus amortized premium, which approximates
market value; (d) dividend income is recorded on the ex-dividend date; (e)
interest income, adjusted for accretion of original issue or market discount,
is recorded on the accrual basis; (f) gains or losses on the sale of securities
are calculated by using the specific identification method; (g) dividends and
distributions to shareholders are recorded on the ex-dividend date; (h) the
accounting records are maintained in U.S. dollars. All assets and liabilities
denominated in foreign currencies are translated into U.S. dollars based on the
rate of exchange of such currencies against U.S. dollars on the date of
valuation. Purchases and sales of securities, and income and expenses are
translated at the rate of exchange quoted on the respective date that such
transactions are recorded. Differences between income and expense amounts
recorded and collected or paid are recorded as currency gains or losses; (i)
the character of income and gains to be distributed are determined in
accordance with income tax regulations which may differ from generally accepted
accounting principles; (j) the Fund intends to comply with the applicable
provisions of the Internal Revenue Code of 1986, as amended, pertaining to
regulated investment companies and to make distributions of taxable income
sufficient to relieve the Fund from substantially all Federal income and excise
taxes; and (k) estimates and assumptions are required to be made regarding
assets, liabilities and changes in net assets resulting from operations when
financial statements are prepared. Changes in the economic environment,
financial markets and any other parameters used in determining these estimates
could cause actual results to differ.

2. Management Agreement and Transactions with Affiliated Persons

Salomon Brothers Asset Management Inc ("SBAM"), a wholly owned subsidiary of
Salomon Brothers Holding Company Inc., which, in turn, is wholly owned by Salo-
mon Smith Barney Holdings, Inc. ("SSBH"), acts as investment manager to the
Fund. Under the investment management agreement, the Fund pays an investment
management fee calculated at the annual rate of 0.75% of its average daily net
assets. This fee is calculated daily and paid monthly.

For the six months ended June 30, 2000, SBAM waived a portion of the management
fees amounting to $25,138.


                                                                              13
<PAGE>

SBAM also acts as administrator to the Fund. As compensation for its services
the Fund pays SBAM a fee calculated at an annual rate of 0.05% of its average
daily net assets. This fee is calculated daily and paid monthly. SBAM has
delegated its responsibilities as administrator to SSB Citi Fund Management LLC
("SSBC"), an affiliate of SBAM, pursuant to a Sub-Administration Agreement
between SBAM and SSBC.

CFBDS, Inc. acts as the Fund's distributor. For the six months ended June 30,
2000, Salomon Smith Barney Inc. ("SSB"), another subsidiary of SSBH, received
no brokerage commissions from the Fund.

3. Investments

During the six months ended June 30, 2000, the aggregate cost of purchases and
proceeds from sales of investments (including maturities, but excluding short-
term securities) were as follows:

<TABLE>
<S>                                                                   <C>
Purchases............................................................ $3,907,307
                                                                      ==========

</TABLE>

At June 30, 2000, the aggregate gross unrealized appreciation and depreciation
of investments for Federal income tax purposes were substantially as follows:

<TABLE>
<S>                                                                <C>

</TABLE>

4. Repurchase Agreements

The Fund purchases (and its custodian takes possession of) U.S. government se-
curities from banks and securities dealers subject to agreements to resell the
securities to the seller at a future date (generally, the next business day) at
an agreed-upon higher repurchase price. The Fund requires maintenance of the
market value of the collateral in amounts at least equal to the repurchase
price.

5. Reverse Repurchase Agreements

The Fund may enter into reverse repurchase agreements. A reverse repurchase
agreement involves a sale by the Fund of securities that it holds with an
agreement by the Fund to repurchase the same securities at an agreed upon price
and date. A reverse repurchase agreement involves risk that the market value of
the securities sold by the Fund may decline below the repurchase price of the
securities. The Fund will establish a segregated account with its custodian, in
which the Fund will maintain cash or other liquid securities with respect to
the reverse repurchase agreements.

During the six months ended June 30, 2000, the Fund did not enter into any re-
verse repurchase agreements.

6. Options Contracts

The Fund may from time to time enter into options contracts. Premiums paid when
put or call options are purchased by the Fund, represent investments, which are
marked-to-market daily. When a purchased option expires, the Fund will realize
a loss in the amount of the premium paid. When the Fund enters into a closing
sales transaction, the Fund will realize a gain or loss depending on whether
the proceeds from the closing sales transaction are greater or less than the
premium paid for the option. When the Fund exercises a put option, it will re-
alize a gain or loss from the sale of the underlying security and the proceeds
from such sale will be decreased by the premium originally paid. When the Fund
exercises a call option, the cost of the security which the Fund purchases upon
exercise will be increased by the premium originally paid.

At June 30, 2000, the Fund did not hold any purchased call or put options.

When the Fund writes a call or put option, an amount equal to the premium
received by the Fund is recorded as a liability, the value of which is marked-
to-market daily. When a written option expires, the Fund realizes a gain equal
to the amount of the premium received. When the Fund enters into a closing
purchase transaction, the Fund realizes a gain or loss depending upon whether
the cost of the closing transaction is greater or less than the premium
originally received, without regard to any unrealized gain or loss on the
underlying security, and the liability related to such option is eliminated.
When a written call option is exercised the proceeds of the security sold will
be increased by the premium originally received. When a written put option is
exercised, the amount of the premium originally received will reduce the cost
of the security which the Fund purchased upon exercise. When written index
options are exercised, settlement is made in cash.

The Fund enters into options for hedging purposes. The risk associated with
purchasing options is limited to the premium originally paid. The risk in
writing a covered call option is that the Fund gives up the opportunity to
participate in any increase in the price of the underlying security beyond the
exercise price. The risk in writing a put option is that the Fund is exposed to
the risk of loss if the market price of the underlying security declines.

During the six months ended June 30, 2000, the Fund did not write any call or
put option contracts.

7. Securities Traded on a When Issued Basis

The Fund may from time to time purchase securities on a when-issued basis. In a
when-issued transaction, the Fund commits to purchasing securities which have
not yet been issued by the issuer. Securities purchased on a when-issued basis,
are not settled until they are delivered to the Fund. Beginning on the date the
Fund enters into the when-issued transaction, cash or other liquid securities
are segregated to cover the amount of the purchase price of the when-issued
security. These transactions are subject to market fluctuations and their
current value is determined in the same manner as for other securities.

At June 30, 2000, the Fund did not hold any when-issued securities.

8. Securities Traded on a To-Be-Announced Basis

The Fund may trade securities on a to-be-announced ("TBA") basis. In a TBA
transaction, the Fund commits to purchasing or selling securities for which
specific information is not yet known at the time of the trade, particularly
the face amount and maturity date in Government National Mortgage Association
("GNMA") transactions. Securities purchased on a TBA basis are not settled
until they are delivered to the Fund, normally 15 to 45 days later. Beginning
on the date the Fund enters into a TBA transaction, cash or other liquid
securities are segregated in the amount of the TBA transaction. These
transactions are subject to market fluctuations and their current value is
determined in the same manner as for other securities.

At June 30, 2000, the Fund did not hold any TBA securities.

                                                                              15

9. Lending of Securities

The Fund may lend its securities to brokers, dealers and other financial
organizations. The Fund has an agreement with its custodian whereby the
custodian may lend securities owned by the Fund to brokers, dealers and other
financial organizations. Fees earned by the Fund on securities lending are
recorded in interest income. Loans of securities by the Fund are collateralized
by cash or other liquid securities that are maintained at all times in an
amount at least equal to the current market value of the loaned securities,
plus a margin which may vary depending on the type of securities loaned. The
custodian establishes and maintains the collateral in a segregated account. The
Fund maintains exposure for the risk of any losses in the investment of amounts
received as collateral.

At June 30, 2000, the Fund did not have any securities on loan.

10. Loan Participations

The Fund may invest in loans arranged through private negotiation between one
or more financial institutions. The Fund's investment in any such loan may be
in the form of a participation in or an assignment of the loan.

In connection with purchasing participations, the Fund generally will have no
right to enforce compliance by the borrower with the terms of the loan
agreement relating to the loan, nor any rights of set-off against the borrower,
and the Fund may not benefit directly from any collateral supporting the loan
in which it has purchased the participation. As a result, the Fund will assume
the credit risk of both the borrower and the lender that is selling the
participation. In the event of the insolvency of the lender selling the
participation, the Fund may be treated as a general creditor of the lender and
may not benefit from any set-off between the lender and the borrower.

At June 30, 2000, the Fund held loan participations with a total cost of
$171,107.

11. Capital Loss Carryforward

At December 31, 1999, the Fund had, for Federal income tax purposes, a capital
loss carryforward of approximately $227,000, available to offset future capital
gains. To the extent that these carryforward losses can be used to offset net
realized capital gains, such gains, if any, will not be distributed. Expiration
occurs on December 31 of the year indicated:

12. Capital Stock

At June 30, 2000, the Series had 10,000,000,000 shares of capital stock autho-
rized with a par value of $0.001 per share. Each share represents an equal pro-
portionate interest and has an equal entitlement to any dividends and distribu-
tions made by the Fund.

Our Message to You

DEAR SHAREHOLDER:

We are pleased to provide you with the semi-annual report for the Salomon
Brothers Variable Strategic Bond Fund ("Fund") for the period ended June 30,
2000. This letter discusses general economic and market conditions as well as
Fund highlights during the reporting period(1). A detailed summary of
performance and current Fund holdings can be found in the appropriate sections
that follow. We hope you find this report useful and informative.

INVESTMENT STRATEGY & PERFORMANCE UPDATE

The Fund's primary objective is to seek a high level of current income, with
capital appreciation as a secondary objective. The Fund seeks to achieve its
objectives by investing in a globally diverse portfolio through allocations to
segments of the fixed-income market that the manager believes will best
contribute to the achievement of the Fund's investment objectives. Tactical
allocations may include U.S. and non-U.S. investment-grade, high-yield and
emerging market debt securities.

For the six months ended June 30, 2000, the Fund returned 2.48%. In comparison,
the Salomon Smith Barney Broad Investment-Grade ("BIG") Bond Index(2), returned
3.92% and the Lehman Brothers Aggregate Bond Index(3)returned 3.99%.

Emerging market debt returned 8.10% for the period as measured by the J.P.
Morgan Emerging Markets Bond Index Plus ("EMBI+")(4). Rising oil prices and
rising interest rates were the predominant fundamental factors impacting returns
during the year. Individual country returns were dominated by Russia, which
gained 49.78%. Overall market performance was good with many countries
generating positive returns although no countries generated returns approaching
Russia's.

The performance of emerging debt markets was particularly strong in light of the
difficult fixed-income environment. The Federal Reserve Board ("Fed") raised
interest rates three times during the period, moving the federal funds

rate/5/ from 5.50% to 6.50%. This aggressive stance by the Fed was an attempt to
slow the rate of U.S. economic growth and keep inflation under control. The
aggressive Fed activity and widening spreads led to subpar returns in most
fixed-income asset classes other than emerging markets debt.

The high-yield bond market returned a negative 1.42% for the period, as reported
by the Salomon Smith Barney High Yield Market Index. As the Fed hiked interest
rates by 25 basis points/6/ in February and the tech-laden Nasdaq Composite
Index/7/ turned in a relatively strong performance early in calendar year 2000,
a string of mutual fund outflows ensued as investors fled the interest rate-
sensitive fixed-income markets for the strong equity markets. As the U.S. equity
markets became more volatile in March and April and the Fed announced a 50 basis
point interest rate increase with a tightening bias in May, mutual fund outflows
intensified as investors focused on the potential for further interest rate
increases. Investors also increasingly considered the possibility of a cyclical
downturn in the near term, which would exacerbate already high default rates. As
a result, mutual fund outflows for the period totaled $5.9 billion. In June,
however, benign economic data and a more passive Fed mitigated interest rate
concerns while the high absolute yields available in the high-yield market
attracted investors from the volatile equity markets.

For the six months ended June 30, 2000, the top performing sectors in the high-
yield market included telecommunications, energy, technology, utilities and
gaming. Telecommunications performance was driven by explosive industry growth,
continued mergers and acquisitions and equity investment activity. High product
prices supported positive performance in energy. Technology's performance
benefited from good fourth quarter results and the popularity of the sector in
the equity markets early in the period. Utilities and gaming, which are
generally composed of higher rated issuers, benefited from investors' preference
for higher-quality issues.

The most significant underperforming sectors consisted of automotive,
steel/metals, capital goods, leisure/lodging, supermarkets/drugstores and
services/other. Automotive was adversely affected by weakness in the parts
aftermarket. Steel/metal's performance was hurt by product price weakness.
Additionally, automotive, steel/metals and capital goods were negatively
impacted by increased cyclical concerns. Leisure/lodging was adversely

affected by operating difficulties at several issuers resulting from
overcapacity in the theatre operator sector. Supermarkets/drugstores performance
was adversely affected by difficulties at Rite Aid and Pathmark.

While inflation has edged higher this year, the most recent price data has not
aggravated the picture and there is a reasonable chance that if demand is
cooling, an important source of potential wage and price pressures would be
contained. Thus, with a lot of tightening under its belt, and some tentative
signs that it's having an effect while inflation is still reasonably low, the
Fed can maintain that a pause may be warranted. Whatever their immediate
intentions, officials likely still see the risks toward higher inflation. The
slowing signs are too tentative, especially in the labor markets. We therefore
anticipate at least a quarter-point of further tightening will be forthcoming
this year, pushing the funds rate to 6.75% or higher.

Thank you for your investment in the Salomon Brothers Variable Strategic Bond
Fund. We look forward to helping you pursue your financial goals in the new
century.

1. Organization and Significant Accounting Policies

Salomon Brothers Variable Strategic Bond Fund ("Fund"), is a separate
diversified investment portfolio of the Salomon Brothers Variable Series Funds
Inc ("Series") whose primary investment objective is to seek a high level of
current income and secondarily capital appreciation. The Series, a Maryland
corporation, is registered under the Investment Company Act of 1940, as amended
("1940 Act"), as an open-end management investment company and consists of this
Fund and seven other investment portfolios: Salomon Brothers Variable Total
Return Fund, Salomon Brothers Variable High Yield Bond Fund, Salomon Brothers
Variable Investors Fund, Salomon Brothers Variable Capital Fund, Salomon
Brothers Variable Small Cap Growth Fund, Salomon Brothers Variable U.S.
Government Income Fund and Salomon Brothers Variable Asia Growth Fund. The U.S.
Government Income Fund and Asia Growth Fund have not yet commenced operations.
The financial statements and financial highlights for the other investment
portfolios are presented in separate shareholder reports. The Fund and each
other investment portfolio of the Series is offered exclusively for use with
certain variable annuity and variable life insurance contracts offered through
the separate accounts of various life insurance companies and qualified pension
and retirement plans.

The significant accounting policies consistently followed by the Fund are: (a)
security transactions are accounted for on trade date; (b) securities traded on
national securities markets are valued at the closing prices on such markets;
securities traded in the over-the-counter market and securities for which no
sales price was reported are valued at the mean of the current bid and asked
prices; debt securities are valued using either prices or estimates of market
values provided by market makers or independent pricing services; securities
and assets for which market quotations are not readily available are valued at
fair value as determined in good faith by or under the direction of the Board
of Directors of the Fund; (c) securities maturing within 60 days are valued at
cost plus accreted discount, or minus amortized premium, which approximates
market value; (d) dividend income is recorded on the ex-dividend date; (e)
interest income, adjusted for accretion of original issue and market discount,
is recorded on the accrual basis; (f) gains or losses on the sale of securities
are calculated by using the specific identification method; (g) dividends and
distributions to shareholders are recorded on the ex-dividend date; (h) the
accounting records are maintained in U.S. dollars. All assets and liabilities
denominated in foreign currencies are translated into U.S. dollars based on the
rate of exchange of such currencies against U.S. dollars on the date of
valuation. Purchases and sales of securities, and income and expenses are
translated at the rate of exchange quoted on the respective date that such
transactions are recorded. Differences between income and expense amounts
recorded and collected or paid are recorded as currency gains or losses;
(i) the character of income and gains to be distributed are determined in
accordance with income tax regulations which may differ from generally accepted
accounting principles. At December 31, 1999, reclassifications were made to the
Fund's capital accounts to reflect permanent book/tax differences and income
and gains available for distributions under income tax regulations. Net
investment income, net realized gains and net assets were not affected by this
change; (j) the Fund intends to comply with the applicable provisions of the
Internal Revenue Code of 1986, as amended, pertaining to regulated investment
companies and to make distributions of taxable income sufficient to relieve the
Fund from substantially all Federal income and excise taxes; and (k) estimates
and assumptions are required to be made regarding assets, liabilities and
changes in net assets resulting from operations when financial statements are
prepared. Changes in the economic environment, financial markets and any other
parameters used in determining these estimates could cause actual results to
differ.

Organization costs amounting to $31,250 were incurred with the organization of
the Fund. These costs are being amortized ratably over a five year period from
commencement of operations.

2. Management Agreement and Transactions with Affiliated Persons

Salomon Brothers Asset Management Inc ("SBAM"), a wholly owned subsidiary of
Salomon Brothers Holding Company Inc., which, in turn, is a wholly owned
subsidiary of Salomon Smith Barney Holdings, Inc. ("SSBH"), acts as investment
manager to the Fund. Under the investment management agreement, the Fund pays
an investment management fee calculated at the annual rate of 0.75% of its
average daily net assets. This fee is calculated daily and paid monthly.
Salomon Brothers Asset Management, Ltd. ("SBAM Ltd."), an affiliate of SBAM,
provides certain advisory services to SBAM for the benefit of the Fund. SBAM
Ltd. is compensated by SBAM at no additional expense of the Fund.

For the six months ended June 30, 2000, SBAM waived a portion of its management
fees amounting to $26,216.

SBAM also acts as administrator to the Fund. As compensation for its services
the Fund pays SBAM a fee calculated at an annual rate of 0.05% of its average
daily net assets. This fee is calculated daily and paid monthly. SBAM has
delegated its responsibilities as administrator to SSB Citi Fund Management LLC
("SSBC"), an affiliate of SBAM, pursuant to a Sub-Administration Agreement
between SBAM and SSBC.

CFBDS, Inc. acts as the Fund's distributor. For the six months ended June 30,
2000, Salomon Smith Barney Inc., another subsidiary of SSBH, did not receive
any brokerage commissions from the Fund.

4. Repurchase Agreements

The Fund purchases (and its custodian takes possession of) U.S. government se-
curities from banks and securities dealers subject to agreements to resell the
securities to the seller at a future date (generally, the next business day) at
an agreed-upon higher repurchase price. The Fund requires maintenance of the
market value of the collateral in amounts at least equal to the repurchase
price.

5. Reverse Repurchase Agreements

The Fund may enter into reverse repurchase agreements. A reverse repurchase
agreement involves a sale by the Fund of securities that it holds with an
agreement by the Fund to repurchase the same securities at an agreed upon price
and date. A reverse repurchase agreement involves risk that the market value of
the securities sold by the Fund may decline below the repurchase price of the
securities. The Fund will establish a segregated account with its custodian, in
which the Fund will maintain cash or other liquid securities with respect to
the reverse repurchase agreements.

During the six months ended June 30, 2000, the Fund did not enter into any re-
verse repurchase agreements.

6. Forward Foreign Currency Contracts

At June 30, 2000, the Fund had open forward foreign currency contracts as de-
scribed below. The Fund bears the market risk that arises from changes in for-
eign currency exchange rates. The unrealized gain (loss) on the contracts re-
flected in the accompanying financial statements were as follows:

7. Options Contracts

The Fund may from time to time enter into options contracts. Premiums paid when
put or call options are purchased by the Fund, represent investments, which are
marked-to-market daily. When a purchased option expires, the Fund will realize
a loss in the amount of the premium paid. When the Fund enters into a closing
sales transaction, the Fund will realize a gain or loss depending on whether
the proceeds from the closing sales transaction are greater or less than the
premium paid for the option. When the Fund exercises a put option, it will re-
alize a gain or loss from the sale of the underlying security and the proceeds
from such sale will be decreased by the premium originally paid. When the Fund
exercises a call option, the cost of the security which the Fund purchases upon
exercise will be increased by the premium originally paid.

At June 30, 2000, the Fund did not have any open purchased call or put option
contracts.

When the Fund writes a call or put option, an amount equal to the premium re-
ceived by the Fund is recorded as a liability, the value of which is marked-to-
market daily. When a written option expires, the Fund realizes a gain equal to
the amount of the premium received. When the Fund enters into a closing pur-
chase transaction, the Fund realizes a gain or loss depending upon whether the
cost of the closing transaction is greater or less than the premium originally
received, without regard to any unrealized gain or loss on the underlying secu-
rity, and the liability related to such option is eliminated. When a written
call option is exercised the proceeds of the security sold will be increased by
the premium originally received. When a written put option is exercised, the
amount of the premium originally received will reduce the cost of the security
which the Fund purchased upon exercise. When written index options are exer-
cised, settlement is made in cash.

The Fund enters into options for hedging purposes. The risk associated with
purchasing options is limited to the premium originally paid. The risk in
writing a covered call option is that the Fund gives up the opportunity to
participate in any increase in the price of the underlying security beyond the
exercise price. The risk in writing a put option is that the Fund is exposed to
the risk of loss if the market price of the underlying security declines.

During the six months ended June 30, 2000, the Fund did not write any call or
put option contracts.

                                                                              17

8. Securities Traded on a When Issued Basis

The Fund may from time to time purchase securities on a when-issued basis. In a
when-issued transaction, the Fund commits to purchasing securities which have
not yet been issued by the issuer. Securities purchased on a when-issued basis,
are not settled until they are delivered to the Fund. Beginning on the date the
Fund enters into the when-issued transaction, cash or other liquid securities
are segregated to cover the amount of the purchase price of the when-issued
security. These transactions are subject to market fluctuations and their
current value is determined in the same manner as for other securities.

At June 30, 2000, the Fund did not hold any when-issued securities.

9. Securities Traded on a To-Be-Announced Basis

The Fund may trade securities on a to-be-announced ("TBA") basis. In a TBA
transaction, the Fund commits to purchasing or selling securities which have
not yet been issued by the issuer, particularly the face amount and maturity
date in Government National Mortgage Association ("GNMA") transactions.
Securities purchased on a TBA basis are not settled until they are delivered to
the Fund, normally 15 to 45 days later. Beginning on the date the Fund enters
into a TBA transaction, cash or other liquid securities are segregated in the
amount of the TBA transaction. These transactions are subject to market
fluctuations and their current value is determined in the same manner as for
other securities.

At June 30, 2000, the Fund held TBA securities with a total cost of $6,200,335.

10. Mortgage Dollar Roll Transactions

The Fund may enter into mortgage "dollar rolls" in which the Fund sells
mortgage-backed securities for delivery in the current month and simultaneously
contracts to repurchase substantially similar (same type, coupon and maturity)
securities on a specific future date. The Fund is compensated by a fee paid by
the counterparty. Dollar rolls are accounted for as financing arrangements; the
fee is accrued into interest income ratably over the term of the dollar roll
and any gain or loss on the roll is deferred until disposition of the rolled
security. The average daily balance of dollar rolls outstanding during the six
months ended June 30, 2000 was approximately $4,598,000.

11. Lending of Securities

The Fund may lend its securities to brokers, dealers and other financial
organizations. The Fund has an agreement with its custodian whereby the
custodian may lend securities owned by the Fund to brokers, dealers and other
financial organizations. Fees earned by the Fund on securities lending are
recorded in interest income. Loans of securities by the Fund are collateralized
by cash or other liquid securities that are maintained at all times in an
amount at least equal to the current market value of the loaned securities,
plus a margin which may vary depending on the type of securities loaned. The
custodian establishes and maintains the collateral in a segregated account. The
Fund maintains exposure for the risk of any losses in the investment of amounts
received as collateral.

At June 30, 2000, the Fund did not have any securities on loan.

12. Loan Participations

The Fund may invest in loans arranged through private negotiation between one
or more financial institutions. The Fund's investment in any such loan may be
in the form of a participation in or an assignment of the loan.

In connection with purchasing participations, the Fund generally will have no
right to enforce compliance by the borrower with the terms of the loan
agreement relating to the loan, nor any rights of set-off against the borrower,
and the Fund may not benefit directly from any collateral supporting the loan
in which it has purchased the participation. As a result, the Fund will assume
the credit risk of both the borrower and the lender that is selling the
participation. In the event of the insolvency of the lender selling the
participation, the Fund may be treated as a general creditor of the lender and
may not benefit from any set-off between the lender and the borrower.

At June 30, 2000, the Fund held loan participations with a total cost of
$177,151.

13. Capital Loss Carryforward

At December 31, 1999, the Fund had for Federal income tax purposes approxi-
mately $5,000 of capital loss carryforwards available to offset future realized
gains through December 31, 2007. To the extent that these capital carryforward
losses are used to offset capital gains, it is probable that the gains so off-
set will not be distributed.

14. Capital Stock

At June 30, 2000, the Series had 10,000,000,000 shares of capital stock
authorized with a par value of $0.001 per share. Each share represents an equal
proportionate interest and has an equal entitlement to any dividends and
distributions made by the Fund.

Transactions in shares were as follows:

Our Message to You

DEAR SHAREHOLDER:

We are pleased to provide the semi-annual report for the Salomon Brothers
Variable Small Cap Growth Fund ("Fund") for the period ended June 30, 2000. This
letter discusses general economic and market conditions as well as Fund
highlights during the reporting period. A detailed summary of performance and
current Fund holdings can be found in the appropriate sections that follow. We
hope you find this report useful and informative.

INVESTMENT STRATEGY & PERFORMANCE UPDATE

The Fund seeks long-term growth of capital. The Fund seeks to achieve its
objective by investing primarily in securities of companies with market
capitalizations similar to that of companies included in the Russell 2000
Index(1). For the six months ended June 30, 2000, the Fund returned 21.58%. In
comparison, the Russell 2000 Index returned 3.04% and the Russell 2000 Growth
Index(2)returned 1.23% for the same period. (Please note, past performance is
not indicative of future results. Additionally, index returns do not represent
the Fund's yield.)

MARKET OVERVIEW & PORTFOLIO HIGHLIGHTS

The Fund returned 21.58% during the first half of 2000, significantly
outperforming the Russell 2000 Growth Index in a volatile market. The period was
marked by an early-year surge in technology and biotech stocks followed by a
significant April and May sell-off in the same stocks. Small capitalization
stocks outperformed large capitalization stocks during the first six months of
the year; the Russell 2000 Growth Index rose 1.23% versus a 0.43% decline for
the Standard & Poor's 500 Index(3)("S&P 500"), while the overall Russell 2000
Index rose 3.04%. Consumer cyclicals, technology and media/telecom stocks were,
in our view, the main negative factors, while healthcare and energy stocks
posted strong positive returns. The Fund outperformed its benchmark due to stock
selection in technology, communications, healthcare and financials. The Fund was
about evenly weighted in technology, the benchmark's largest sector, during the
first half of 2000.


------------------

1    The Russell 2000 Index measures the performance of the 2,000 smallest
     companies in the Russell 3000 Index, which represents approximately 8% of
     the total market capitalization of the Russell 3000 Index. An investor
     cannot invest directly in an index.
2    The Russell 2000 Growth Index measures the performance of those Russell
     2000 companies with higher price-to-book ratios and higher forecasted
     growth values. (A price-to-book ratio is the price of a stock dividend
     divided by its net asset value.) An investor cannot invest directly in an
     index.
3    The S&P 500 is a market capitalization-weighted measure of 500 widely held
     common stocks. An investor cannot invest directly in an index.

                                                                               1

MARKET OUTLOOK

As we enter the second half of 2000, market volatility continues but we have
seen a broader-based market than the tech-driven one of late 1999 and early 2000
period. Inflows to small cap mutual funds have slowed from a robust first
quarter pace, but so has the Initial Public Offerings ("IPO") calendar, thereby
avoiding excess supply overhang. We believe that relative valuations versus
large cap stocks are still attractive by most historical measures. We remain
broadly diversified across market sectors, which has helped to limit performance
volatility so far in 2000. While it may be a sound strategy, diversification
does not assure against market loss.

Thank you for your investment in the Salomon Brothers Variable Small Cap Growth
Fund. We look forward to helping you pursue your financial goals in the coming
years.

Sincerely,


/s/ Heath B. McLendon                         /s/ Matthew P. Ziehl

1. Organization and Significant Accounting Policies

Salomon Brothers Variable Small Cap Growth Fund ("Fund") is a separate
diversified investment portfolio of the Salomon Brothers Variable Series Funds
Inc ("Series") whose primary investment objective is to seek long-term growth
of capital. The Series, a Maryland corporation, is registered under the
Investment Company Act of 1940, as amended ("1940 Act"), as an open-end
management investment company and consists of this Fund and seven other
investment portfolios: Salomon Brothers Variable Capital Fund, Salomon Brothers
Variable Total Return Fund, Salomon Brothers Variable High Yield Bond Fund,
Salomon Brothers Variable Strategic Bond Fund, Salomon Brothers Variable
Investors Fund, Salomon Brothers Variable U.S. Government Income Fund and
Salomon Brothers Variable Asia Growth Fund. The U.S. Government Income Fund and
Asia Growth Fund have not yet commenced operations. The financial statements
and financial highlights for the other investment portfolios are presented in
separate shareholder reports. The Fund and each other investment portfolio of
the Series is offered exclusively for use with certain variable annuity and
variable life insurance contracts offered through the separate accounts of
various life insurance companies and qualified pension and retirement plans.

The significant accounting policies consistently followed by the Fund are: (a)
security transactions are accounted for on trade date; (b) securities traded on
national securities markets are valued at the closing prices on such markets;
securities traded in the over-the-counter market and securities for which no
sales price was reported are valued at the mean of the current bid and asked
prices; debt securities are valued using either prices or estimates of market
values provided by market makers or independent pricing services; securities
and assets for which market quotations are not readily available are valued at
fair value as determined in good faith by or under the direction of the Board
of Directors of the Fund; (c) securities maturing within 60 days are valued at
cost plus accreted discount, or minus amortized premium, which approximates
market value; (d) dividend income is recorded on the ex-dividend date; foreign
dividend income is recorded on the ex-dividend date or as soon as practical
after the Fund determines the existence of a dividend declaration after
exercising reasonable due diligence; (e) interest income, adjusted for
accretion of original issue or market discount, is recorded on the accrual
basis; (f) gains or losses on the sale of securities are calculated by using
the specific identification method; (g) dividends and distributions to
shareholders are recorded on the ex-dividend date; (h) the accounting records
are maintained in U.S. dollars. All assets and liabilities denominated in
foreign currencies are translated into U.S. dollars based on the rate of
exchange of such currencies against U.S. dollars on the date of valuation.
Purchases and sales of securities, and income and expenses are translated at
the rate of exchange quoted on the respective date that such transactions are
recorded. Differences between income and expense amounts recorded and collected
or paid are recorded as currency gains or losses; (i) the character of income
and gains to be distributed are determined in accordance with income tax
regulations which may differ from generally accepted accounting principles; (j)
the Fund intends to comply with the applicable provisions of the Internal
Revenue Code of 1986, as amended, pertaining to regulated investment companies
and to make distributions of taxable income sufficient to relieve the Fund from
substantially all Federal income and excise taxes; and (k) estimates and
assumptions are required to be made regarding assets, liabilities and changes
in net assets resulting from operations when financial statements are prepared.
Changes in the economic environment, financial markets and any other parameters
used in determining these estimates could cause actual results to differ.

2. Management Agreement and Transactions with Affiliated Persons

Salomon Brothers Asset Management Inc ("SBAM"), a wholly owned subsidiary of
Salomon Brothers Holding Co. Inc., which, in turn, is wholly owned by Salomon
Smith Barney Holdings, Inc. ("SSBH"), acts as investment manager to the Fund.
Under the investment management agreement, the Fund pays an investment
management fee calculated at the annual rate of 0.75% of its average daily net
assets. This fee is calculated daily and paid monthly.

For the six months ended June 30, 2000, SBAM waived all of its management fees
and reimbursed expenses amounting to $20,701.

SBAM also acts as administrator to the Fund. As compensation for its services
the Fund pays SBAM a fee calculated at an annual rate of 0.05% of its average
daily net assets. This fee is calculated daily and paid monthly. SBAM has
delegated its responsibilities as administrator to SSB Citi Fund Management LLC
("SSBC"), an affiliate of SBAM, pursuant to a Sub-Administration Agreement
between SBAM and SSBC.

CFBDS, Inc. acts as the Fund's distributor. For the six months ended June 30,
2000, there were no brokerage commissions paid to Salomon Smith Barney Inc.
("SSB"), another subsidiary of SSBH.

3. Investments

During the six months ended June 30, 2000, the aggregate cost of purchases and
proceeds from sales of investments (including maturities, but excluding short-
term securities) were as follows:

<TABLE>
<S>                                                                   <C>
Purchases............................................................ $4,398,769
                                                                      ==========

</TABLE>

At June 30, 2000, the aggregate gross unrealized appreciation and depreciation
of investments for Federal income tax purposes were substantially as follows:

<TABLE>
<S>                                                                   <C>
Gross unrealized appreciation........................................ $ 755,387
Gross unrealized depreciation........................................  (272,938)
                                                                      ---------
Net unrealized appreciation.......................................... $ 482,449
                                                                      =========
</TABLE>

4. Repurchase Agreements

The Fund purchases (and its custodian takes possession of) U.S. government
securities from banks and securities dealers subject to agreements to resell
the securities to the seller at a future date (generally, the next business
day) at an agreed-upon higher repurchase price. The Fund requires maintenance
of the market value of the collateral in amounts at least equal to the
repurchase price.

5. Options Contracts

The Fund may from time to time enter into options contracts. Premiums paid when
put or call options are purchased by the Fund, represent investments, which are
marked-to-market daily. When a purchased option expires, the Fund will realize
a loss in the amount of the premium paid. When the Fund enters into a closing
sales transaction, the Fund will realize a gain or loss depending on whether
the proceeds from the closing sales transaction are greater or less than the
premium paid for the option. When the Fund exercises a put option, it will
realize a gain or loss from the sale of the underlying security and the
proceeds from such sale will be decreased by the premium originally paid. When
the Fund exercises a call option, the cost of the security which the Fund
purchases upon exercise will be increased by the premium originally paid.

At June 30, 2000, the Fund held purchased call options with a total cost of
$22,262.


                                                                              11
<PAGE>

Notes to Financial Statements
(unaudited) (continued)

When the Fund writes a call or put option, an amount equal to the premium
received by the Fund is recorded as a liability, the value of which is marked-
to-market daily. When a written option expires, the Fund realizes a gain equal
to the amount of the premium received. When the Fund enters into a closing
purchase transaction, the Fund realizes a gain or loss depending upon whether
the cost of the closing transaction is greater or less than the premium
originally received, without regard to any unrealized gain or loss on the
underlying security, and the liability related to such option is eliminated.
When a written call option is exercised the proceeds of the security sold will
be increased by the premium originally received. When a written put option is
exercised, the amount of the premium originally received will reduce the cost
of the security which the Fund purchased upon exercise. When written index
options are exercised, settlement is made in cash.

The Fund enters into options for hedging purposes. The risk associated with
purchasing options is limited to the premium originally paid. The risk in
writing a covered call option is that the Fund gives up the opportunity to
participate in any increase in the price of the underlying security beyond the
exercise price. The risk in writing a put option is that the Fund is exposed to
the risk of loss if the market price of the underlying security declines.

During the six months ended June 30, 2000, the Fund did not write any call or
put option contracts.

6. Securities Traded on a When Issued Basis

The Fund may from time to time purchase securities on a when-issued basis. In a
when-issued transaction, the Fund commits to purchasing securities which have
not yet been issued by the issuer. Securities purchased on a when-issued basis,
are not settled until they are delivered to the Fund. Beginning on the date the
Fund enters into the when-issued transaction, cash or other liquid securities
are segregated to cover the amount of the purchase price of the when-issued
security. These transactions are subject to market fluctuations and their
current value is determined in the same manner as for other securities.

At June 30, 2000, the Fund did not hold any when-issued securities.

7. Securities Traded on a To-Be-Announced Basis

The Fund may trade securities on a "to-be-announced" ("TBA") basis. In a TBA
transaction, the Fund commits to purchasing or selling securities for which
specific information is not yet known at the time of the trade, particularly
the face amount and maturity date in Government National Mortgage Association
("GNMA") transactions. Securities purchased on a TBA basis are not settled
until they are delivered to the Fund, normally 15 to 45 days later. Beginning
on the date the Fund enters into a TBA transaction, cash or other liquid
securities are segregated in the amount of the TBA transaction. These
transactions are subject to market fluctuations and their current value is
determined in the same manner as for other securities.

At June 30, 2000, the Fund did not hold any TBA securities.

8. Lending of Securities

The Fund may lend its securities to brokers, dealers and other financial
organizations. The Fund has an agreement with its custodian whereby the
custodian may lend securities owned by the Fund to brokers, dealers and other
financial organizations. Fees earned by the Fund on securities lending are
recorded in interest income. Loans of securities by the Fund are collateralized
by cash or other liquid securities that are maintained at all times in an
amount at least equal to the current market value of the loaned securities,
plus a margin which may vary depending on the type of securities loaned. The
custodian establishes and maintains the collateral in a segregated account. The
Fund maintains exposure for the risk of any losses in the investment of amounts
received as collateral.

At June 30, 2000, the Fund did not have any securities on loan.

9. Capital Stock

At June 30, 2000, the Series had 10,000,000,000 shares of capital stock
authorized with a par value of $0.001 per share. Each share represents an equal
proportionate interest and has an equal entitlement to any dividends and
distributions made by the Fund.

Transactions in shares were as follows:

    December 31, 1999.
(3) SBAM has waived all or part of its management fees for the six months ended
    June 30, 2000 and the period ended December 31, 1999. In addition, SBAM has
    reimbursed the Fund for $20,701 and $27,494 in expenses for the six months
    ended June 30, 2000 and the period ended December 31, 1999, respectively.
    If such fees were not waived and expenses not reimbursed, the per share

(4) Total returns do not reflect expenses associated with the separate account
    such as administrative fees, account charges and surrender charges which,
    if reflected, would reduce the total returns for all periods shown. Total
    returns may also reflect a voluntary expense cap imposed by Salomon
    Brothers Asset Management Inc to limit total Fund operating expenses.
    Absent this expense cap, total returns for the Fund would be lower. Expense
    caps may be revised or terminated.
(5) As a result of a voluntary expense limitation, expense ratios will not
    exceed 1.50%.
